Why would a normie watch porn once a day if he's not addicted? Porn is uninteresting and incredibly grotesque. It's not mandatory for life like eating or breathing or toileting. Watching porn is immoral -- not for any Christcuck reason, but because you're using another person's body for your sexual pleasure without their expressly given, enthusiastic, conscious consent. Porn also desensitizes the viewer to sexualized nudity and sex acts; eventually the nudity and sex that was once extreme enough for you to get off is no longer enough, which leads to escalation towards weird paraphilias such as BDSM, crossdressing, diapers, furries, and in some cases pedophilia. As it is, "teen porn", one of the most popular porn genres, is basically CP all but legally since it uses women who look at most 15 or 16 but are actually 18 and over. The act of watching porn itself is voyeurism -- voyeurism is a paraphilia, and paraphilias tend to cluster, which means all porn users automatically have a degenerate kink and are at risk of developing more.
If you use any amount of porn as an adult, you are addicted, full stop. Looking at it a few times out of curiosity as a teenager and never again is understandable, but watching it on a regular basis as an adult is addiction and degeneracy. Porn addiction in particular requires some degree of sociopathy, given the vileness of the material, so adults who watch porn are not just degenerates, but also sociopaths.
